To get the most out of this book

You will need Debian Linux or Ubuntu Linux installed on a virtual machine or as your main operating system on your computer. Other software we use is either already installed as a default toolset, or we will show you where to get it to install it on your system.

It is assumed that you have some basic knowledge of Linux and its command-line interface. Familiarity with shell scripting and basic programming concepts would also be helpful. Additionally, some understanding of IT infrastructure and how it is managed is recommended, as well as some exposure to software development practices.

This book is aimed at beginners in the DevOps world, and it assumes that you are eager to learn about the tools and concepts that are commonly used in this field. By the end of this book, you will have gained a solid understanding of how to manage infrastructure using IaC tools such as Terraform and Atlantis, as well as how to automate repetitive tasks using Ansible and Bash scripting. You will also learn how to set up logging and monitoring solutions to help you maintain and troubleshoot your infrastructure.
